Morphological parameters included simulated keratometry and the cone location magnitude index from the axial map (aCLMI) and tangential map (tCLMI). Parameters were extracted using software designed to read and process topographic maps.

RESULTS: There were no significant differences between preoperatively and postoperatively in mean CH (7.7 mm Hg +/- 1.4 [SD] versus 7.4 +/- 1.4 mm Hg) or mean CRF (6.6 +/- 1.8 mm Hg versus 6.1 +/- 1.4 mm Hg). Only 2 ORA signal parameters were significantly different. Topographic parameters with significant decreases were minimum central keratometry (K) (mean change -5.8 +/- 2.9 diopters [D]) (P<.001),

minimum central K (mean change -5.8 +/- 2.3 D) (P<.001), mean aCLMl (9.6 +/- 2.7 preoperatively versus 7.7 +/- 2.5 postoperatively) (P<.009), and mean tCLMI (18.9 +/- 2.8 versus 12.9 +/- 4.4) (P<.002). The only significant correlation between

biomechanical and AZD8055 datasheet topographic parameters was postoperative ORA infrared signal peak 1 and postoperative aCLMI.

CONCLUSIONS: Intrastromal corneal ring implantation significantly decreased corneal curvature, with preoperative values predicting magnitude THZ1 of change. However, it did not alter the viscoelastic biomechanical parameters of CH and CRF.”
“We have used the magnetooptical Kerr effect to investigate the shape of the hysteresis loops of thin GaMnAs films grown on substrates with different buffer layers. Depending on whether the easy axis of magnetization is in the plane of the thin film or out of the plane, and depending on the orientation of the external magnetic field with respect to the crystallographic axes, a great variety of hysteresis

loops is observed. Because magnetooptical effects depend linearly on specific components of the magnetization, it has been possible to determine the orientation of the magnetization with varying magnetic field. The experimental findings are very well described by the Stoner-Wohlfarth model of coherent magnetization rotation, yielding precise values for the anisotropy constants. We present this model and its use in the context of magnetooptical measurements as a relatively simple and straightforward method for establishing magnetization find more parameters of ferromagnetic semiconductors in thin film form.

“Brucella spp. are Gram-negative, facultative intracellular bacterial pathogens that cause abortion in livestock and undulant fever in humans worldwide. Brucella abortus strain 2308 is a pathogenic strain that affects cattle and humans. Currently, there are no efficacious human vaccines available. However, B. abortus strain RB51, which is approved by the USDA, is a live-attenuated rough vaccine against bovine brucellosis. Live strain RB51 induces protection via CD4+ and CD8+ T-cell-mediated immunity. To generate an optimal T-cell response, strong innate immune responses by dendritic cells (DCs) are crucial.
